On S∖ D we construct Hermitian metrics which are flat along the leaves of the canonical foliation and study their evolution under the Chern-Ricci flow. For Enoki surfaces, we construct an immortal normalised solution which, on every compact sublevel of the natural exhaustion, converges in the Gromov-Hausdorff sense to the elliptic base endowed with an explicit flat metric. For Kato surfaces of intermediate type, the affine Green model and its finite-index extension give, under the assumption 0<μ<2, an explicit normalised solution which, on every compact Green block, collapses in the Gromov-Hausdorff sense to a circle. In the Enoki case the limiting area is 2πb₂(S); in the intermediate case the length of the limiting circle is determined by the Green and leafwise monodromies.Ricci flowGeneralized & G₂ flowsLimit spaces & RCDLong-time existence & convergence https://neckpinch.com/papers/2503.16936/arxiv:2503.16936Fri, 21 Mar 2025 00:00:00 GMTDaniele Angella — In this survey, we consider various analytic problems related to the geometry of the Chern connection on Hermitian manifolds, such as the existence of metrics with constant Chern-scalar curvature, generalizations of the Kähler-Einstein condition to the non-Kähler setting, and the convergence of the Chern-Ricci flow on compact complex surfaces.Ricci flowGeneralized & G₂ flowsEinstein metricsKähler geometryScalar curvatureKähler–Einstein & K-stability
